Decision-Making Factors for Systemic Therapies in Atopic Dermatitis: A Clinical Review

<u><b><i></i></b></u> Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease that significantly impairs quality of life. In recent years, treatment has advanced from broad immunosuppressants to targeted biologics and small-molecule therapies that modulate type 2 inflammation and itch signaling. Dupilumab, tralokinumab, lebrikizumab, and nemolizumab are now FDA-approved biologics with demonstrated efficacy and favorable long-term safety, while oral Janus kinase inhibitors (JAKis) such as abrocitinib, upadacitinib, and baricitinib often provide rapid disease control but carry black-box warnings. Comparative trials highlight faster itch relief with JAKis but durable disease control and safety advantages with biologics. The expanding treatment landscape necessitates individualized therapy selection. Key clinical considerations include patient age, pregnancy status, infection, malignancy, or thromboembolic risk, comorbid conditions, and history of adverse effects. Equally important are patient-centered preferences such as dosing frequency, route of administration, storage logistics, and willingness to self-inject. Access and affordability also influence care, with many manufacturers offering copay support and patient assistance programs. Future directions emphasize head-to-head comparative studies, biomarker development for precision treatment, and equitable access to advanced therapies. This narrative review synthesizes current evidence on biologics and JAKis in AD, outlining efficacy, safety, and practical decision-making factors to guide dermatologists in aligning therapies with both clinical context and patient priorities.
